![]() Fatal familial insomnia is a hereditary prion (a type of protein) disease that attacks a particular chromosome. The main causes of damage to your thalamus include:Ĭertain conditions that are affected by or damage your thalamus include: Thalamic pain syndrome (tingling or burning pain). ![]() Vision problems, including vision loss or light sensitivity.Thalamic aphasia (jumbled words, meaningless speech).Sleep disorders, such as insomnia and fatal familial insomnia (inability to sleep, leading to death).Trouble processing sensory information.Trouble with attention, loss of alertness.Loss of ability to understand language or speak ( aphasia).Lack of interest or enthusiasm (apathy).Symptoms of damage to your thalamus include: So, damage to your thalamus can affect many functions. Your thalamus then sends this information to other parts of your brain. ![]() Your thalamus is a central relay station for receiving incoming sensory and motor information. Makes up the outer covering of the thalamus influences the activity of other nuclei within the thalamus Project to the substantia nigra, premotor cortex, reticular formulation and corpus striatumĬognitive, determine prominent visual stimuli Relay motor information about movement/tremor Relay sensory information (pain, temperature and touch) Projects to the prefrontal cortex and limbic system This chart names some of the best known nuclei, their function and to what area of your cerebral cortex the information is ultimately sent.Ĭommunicates with what section of your cerebral cortexĬonnected to the hypothalamus projects to the cingulate gyrusĮmotional behavior and memory attention, organization, planning and higher cognitive thinking Specialized areas of your thalamus, called nuclei, are each responsible for processing different sensory or motor impulses received from your body and then sending the selected information through nerve fibers to the related area of your cerebral cortex for interpretation. Sensory impulses (“information”) travel through nerve fibers from your body through brain structures to your thalamus. Your thalamus also contributes to perception and plays a role in sleep and wakefulness. Your thalamus is connected with structures of your limbic system, which is involved in processing and regulating emotions, formation and storage of memories, sexual arousal and learning. Role in thinking (cognition) and memory. ![]() Your thalamus plays a role in keeping you awake and alert. Your thalamus helps decide what to focus on among the vast amount of information that it receives. Similar to sensory information, motor pathways all pass through your thalamus.
